Abstract

Abstract: Schizophrenia is a major mental disorder that affects approximately 1% of the population worldwide. Cognitive deficits are a key feature of the disorder and a primary cause of long-term disability. Over the past decades, significant literature has accumulated demonstrating impairments in early auditory perceptual processes in schizophrenia. In this review, we first describe early auditory dysfunction in schizophrenia from both a behavioral and neurophysiological perspective and examine their interrelationship with both higher order cognitive constructs and social cognitive processes. Then, we provide insights into underlying pathological processes, especially in relationship to glutamatergic and N-methyl-D -aspartate receptor (NMDAR) dysfunction models. Finally, we discuss the utility of early auditory measures as both treatment targets for precision intervention and as translational biomarkers for etiological investigation. Altogether, this review points out the crucial role of early auditory deficits in the pathophysiology of schizophrenia, in addition to major implications for early intervention and auditory-targeted approaches. Highlights: Early auditory processing (EAP) deficits are a core feature of schizophrenia with critical contributions to cognitive impairments. EAP deficits involve impairments at both subcortical and cortical stages of processing. Mismatch negativity (MMN) serves as a translational biomarker for N-methyl-D-aspartate (NMDAR) dysfunction. Undetected EAP deficits may be a critical barrier to functional recovery in schizophrenia
